FIG. 1 illustrates a kart having certain features, aspects andadvantages of the present invention. The kart includes a body 10, whichincludes a first or rear portion 20 and a second or front portion 30.Preferably the front portion 30 is rotatably coupled to the rear portion20. The rear portion 20 includes a seat portion 22 configured to allow arider to be seated thereon. The rear portion 20 also supports at leastone rear wheel 24. In a preferred embodiment, the rear portion 20supports two rear wheels 24 and in other embodiments the rear portion 20can support more than two rear wheels. The rear wheels 24 are coupled tothe bottom of the rear portion 20. In some embodiments, the rear wheels24 are swivel or caster wheels configured to rotate relative to the rearportion 20 about a swivel axis. Preferably, the rear wheels 24 arelocated below and toward a rearward end of or behind the seat portion22. In some embodiments, the rear portion 20 curves upward or extendsupward at the rear end of the rear portion behind the seat portion 22.Preferably, the rear portion 20 also includes an outer shell or coverportion 26. In some embodiments, the outer shell or cover portion 26 islocated in front of and adjacent to the seat portion 22 and can resemblea head of an animal, insect or character, for example.

As illustrated, the outer cover portion 26 preferably includes one ormore openings or window portions 28. In some embodiments, the one ormore openings or window portions 28 are configured to allow a person tosee through the outer cover 26. In one embodiment, the window portions28 comprise a translucent or transparent material. In anotherembodiment, the window portions 28 comprise cut-out portions in theouter cover portion 26. Preferably, the window portions 28 are circularand are located near the front of the outer shell or cover 26. The outershell 26 can also include visual features on the surface of outer shell26 or extending therefrom. For example, the outer shell 26 can includeprotruding features such as protrusions resembling antennae 27 orfeatures painted or printed on the surface such as features resembling amouth 29 or ears. In some embodiments, the outer shell 26 is configuredwith visual features that resemble an animal, insect or cartooncharacter.

As illustrated, the front portion 30 includes a coupling portion 38 thatis configured to be coupled to the rear portion 20. The front portion 30also supports at least one front wheel 34. In a preferred embodiment,the front portion 30 supports two front wheels 34 and in other preferredembodiments, the front portion 30 supports only one front wheel or morethan two front wheels 34. Preferably, the front portion 30 also supportsa handlebar assembly 32 configured to allow a user to move and/or steerthe kart. The handlebar assembly 32 preferably extends from the front ofthe kart backwards toward the rear portion 20 so that a user can accessthe handlebar assembly 32 with his or her hands. The handlebar assembly32 also preferably includes grips 36 accessible to the hands of a user.Preferably, the front portion 30 in configured to extend away from therear portion 40 in the forward direction and the handlebar assembly 32is supported by the front portion 30 at a location forward from the rearportion 20 so that a user riding the kart can rest his feet on a portionof the handlebar assembly 32 in front of the rear portion 20. In someembodiments, the handlebar assembly 32 includes a substantially straightportion or portions 45 located near the front of the kart and configuredto support a user's foot as the user rides the kart. Preferably, thehandlebar assembly 32 also includes two end portions 42 that extendbackward toward the rear portion 20 of the kart. Preferably, the endportions 42 also curve or extend upward and include the grips 36 thatare accessible to a user riding the kart.

In some preferred embodiments, the front portion 30 is rotatably coupledto the rear portion 20 and rotates relative to the rear portion 20 aboutan axis. Preferably the axis is generally or substantially verticaland/or normal to the riding surface. Preferably, the front wheels 34 arepositioned behind the axis and under the rear portion 20. Preferably,the entire front portion 30, including the handlebar assembly 32 and thefront wheels 34, rotate about the axis relative to the rear portion 20.Each of the front wheels 34 can also rotate about its own wheel axis.Because the rotational axis and/or contact patch of the front wheels 34is spaced behind the steering axis, oscillating movement or repeatedback-and-forth rotation of the front portion 30 also creates a motiveforce for the kart. In some embodiments, the front wheels 34 can beswivel or caster wheels that are configured to rotate about a swivelaxis relative to the front portion.

As illustrated, the front portion 30 also includes an inner member orinner surface portion 39. Preferably, the inner surface portion 39 movesrelative to the outer shell or cover 26 of the rear portion 20 as thefront portion 30 rotates relative to the rear portion 20. The innersurface 39 is at least partially nested within or covered by the outercover portion 26 and the inner surface 39 preferably has the same,similar or compatible shape as part of the outer cover portion 26. Insome embodiments, the inner surface 39 is curved or spherically shaped(e.g., hemi-spherical) and the outer cover portion 26 is also curved orspherically shaped (e.g., hemi-spherical) so that the two surfaces canbe positioned adjacent to one another and move relative to one another.In a preferred embodiment, the inner surface 39 and the outer coverportion 26 have the same curvature and the inner surface 39 isconfigured to slide along the inside of the outer cover portion 26.Preferably, the inner surface 39 is coupled to the coupling portion 38and extends upward from the coupling portion 38 and front portion 30.

Preferably, a portion of the inner surface 39 is visible through thewindow portion or opening 28 on the outer cover portion 26. In someembodiments, the window portion 28 comprises a translucent ortransparent material that makes the underlying inner surface portion 39visible. In other preferred embodiments, the window portion 28 is a voidor opening in the outer cover portion 26 through which portions of theinner surface 39 are visible. Preferably, the inner surface 39 includesone or more visual features 40 that are visible through the windowportion 28. As the inner surface 39 moves relative to the outer coverportion 26, the visual feature 40 moves relative to the window portion28 which can provide a desired visual effect. For example, in apreferred embodiment, the inner surface 39 includes two visual features40 that resemble eyes or the iris and pupil portions of an eye. Theouter cover portion 26 includes two window portions 28, and one of thevisual features 40 is visible through each of the window portions 28.The visual features 40 that resemble eyes can move side to side relativeto the window portions 28 as the inner surface 39 moves relative to theouter cover portion 26. This results in a visual effect resembling eyesmoving side to side as the handlebar assembly 32 rotates from side toside. This embodiment also results in the desired effect that the eyesor visual features 40 follow the direction of the handlebar assembly 32and front portion 30 as a user steers the kart. Preferably, the visualfeatures 40 move to point in the direction that the kart is moving orbeing steered. In alternative arrangements, a portion of or componentconnected to and movable with the inner surface portion 39 can extend tothe outside of the cover 26, such as through openings (e.g., windowportions 28) or from underneath of the cover 26, such that the exposedportion or component is visible and creates a desired visual effect uponsteering or other movement of the kart. In other arrangements, thevisual feature can be color(s) or symbols (e.g., words) that can moverelative to another portion of the kart (e.g., the cover 26) and can beexposed or hidden as a result of steering or other movement of the kart,for example. Thus, for example, the exposed color could move or couldchange as a result of steering or other movement of the kart. Or, anexposed word(s) or other symbols could changes as a result of steering,such as the words “left” or “right” depending on the steering direction,which could be visible to a user of the kart, if desired.

As illustrated in FIG. 4, in some embodiments the visual features 40 aresubstantially centered within the window portions 28 when the frontportion 30 and handlebar assembly 32 are in a position pointing straightforward relative to the rear portion 20. Preferably the visual features40 resemble eye portions and are centered within the window portions 28when the front portion 30 is in a centered position relative to the rearportion 20 and not rotated to one side or the other.

As illustrated in FIG. 5, in some embodiments the visual features 40move to the right side of the window portions 28 when the handlebarassembly 32 is rotated to the right relative to the rear portion and theinner surface 39 rotates to the right. Preferably, this provides thevisual effect of the visual features 40, which resemble eyes, moving tothe right as the handlebar assembly 32 is steered to the right.

As illustrated in FIG. 6, in some embodiments the visual features 40move to the left side of the window portions 28 when the handlebarassembly 32 is rotated to the left relative to the rear portion and theinner surface 39 rotates to the left. Preferably, this provides thevisual effect of the visual features 40, which resemble eyes, moving tothe left as the handlebar assembly 32 is steered to the left. In otherembodiments, the visual features 40 can move in an opposite directionrelative to the direction of movement of the handlebar assembly 32 orfront portion 30. In some embodiments, the movement of the visualfeatures 40 relative to the window portions 28 can include a verticalcomponent.
